Question

Lauren has a bucket of sidewalk chalk. In the bucket there are 2 green, 8 red, 2 yellow, 4 blue and 4 pieces of white chalk. If she randomly pulls out 6 pieces of chalk, in how many ways can she pull out exactly 2 red chalks and 1 white chalk

Answer 1

32 ways

Explanation:

Since there are 8 red chalks and 4 white chalks.

Then number of ways to select exactly 2 red chalks is; 8C2 = 28 ways

Number of ways to select exactly 1 white chalk is; 4C1 = 4 ways

Total number of ways = 28 + 4 = 32 ways
